OIL-CLEANSING APPARATUS SPECIFICATION forming part of Letters Patent No. 553,710, dated January 28, 1896.

Application filed April 3, 1895.

T0 on whom it may concern:

Be it known that I, DAVID \V. GOULD, a citizen of the United States, residing at \Vashington, .in the District of Columbia, have invented certain new and useful Improvements in Oil-Cleansin g Apparatus, of which the following is a specification, reference being had therein to the accompanying drawings.

M y invention relates to an oil-cleansin g apparatus and it has for its object the production of a cleansing device that will effectively remove from the oil rendered impure by use the foreign substances, thus leaving the oil pure and clean, ready to be again utilized.

The invention will first be described in connection with the accompanying drawings, and then pointed out in the claims.

Figure 1 is a perspective view of my improved oil-cleansing device. Fig. 2 is a vertical central sectional view of the same. Fig. 3 is a sectional view of the inner oil-receptacle. Fig. 4: is a horizontal sectional view of the apparatus, taken on the line so as, Fig. 2. Fig. 5 is a reduced vertical sectional view, taken on the line y 3 Fig. 3, illustrating the manner in which the discharge-pipes converge.

Referring to the drawings, A is a vessel, preferably rectangular, as shown, provided on its front side with ordinary gages 1 and 2 and on the side with a faucet 3. This vessel is provided with a cover B, having an opening at through which oil is poured into the cleanser.

C represents the inner oil-receptacle, all its parts being preferably formed integral. One wall, 5, of this receptacle extends nearly to the bottom of the vessel, while the other wall, 6, is much shorter. These walls are of a width to just fit within the vessel and are provided at their upper ends with overhanging lips 7, adapted to engage the sides of the vessel and hold the receptacle removably in place, as

shown in Fig. 2. To the wall 5, a short distance below its upper end, is secured a plate D, which inclines downward toward wall 6 and is secured thereto, this plate being of a width equal to the interior diameter of the vessel A. Nearthe wall 6 the plate D is provided with a central opening 8, and in this opening is placed Serial No. 544,290. (No model.)

a screen (1. one end to wall 6, is what I term a separating-plate E. This plate is provided on its upper side with a number of projections e, and inclines in a direction opposite to the direction of plate D. Near the wall 5 the end of the plate E is secured to the upper end of a'pipe 9, which at its upper end is the same width as the plate E, but decreases in size until at the lower or discharge end it is circularin form and narrow in cross-section. This pipe 9 extends to near the bottom of the vessel and is so constructed that wall 5 forms one wall of the pipe. A short distance from pipe 9 there is secured to the under side of plate E an auxiliary wall F, which extends to near the bottom of the vessel A, and equal in width to the interior diameter of the vessel, thus dividing the vessel into two chambers below the plate E. A pipe 10, similar to pipe 9, is secured to the wall F and is provided at its lower end with a valve 11, for a purpose hereinafter described. Between the walls 5 and F is placed a screen Gfor screening the impurities from the rising oil.

\Vater being placed in the chambers a and a, the operation of my cleanser is as follows: Oil rendered dirty from use is poured into the vessel through the opening a in the top or cover B. -It drops onto plate D, where it will find its way down the inclined plate and through the opening 8 and screen (I, thus removing some of the impurities. After passing through the screen the oil drops onto the plate E, where the projections e serve to break the oil into globules and also to remove some of the impurities; After leaving the plate E the oil passes down the pipe 9, from which it is discharged into the water in chamber a through which it passes, rising upward through screen G and accumulating on top of the water. lVhen sufficient oil has accumulated to cause the surface to rise to the level of the inlet of pipe 10 it will flow into the pipe. As the lower end of this pipe is protected with a valve no water can get in it, and the oil, when sufficient has accumulated to exert more pressure than the water, will force the valve open and flow out into chamber a, where it will gradually filter through Below plate D, and secured at the water in that chamber and accumulate on its surface, where it may be drawn off through faucet 3 ready for use, the gages l and 2 serving to show the conditions of the oil and water.

The bottom of the vessel just below each chamber is curved downward and at the lowest point is provided with a discharge-pipe 12, permitting the impurities which fall to the bottom to be drawn oft. Jet steam-pipes l'I lead into each chamber, permitting the opcrater to keep the water at an even temperature and also to agitate it to more effectively remox e impurities from the oil.

Though I have described water as the purifying-liquid it is evident that any other purifier could be used with equal facility.

By forming the inner oil-receptacle inte gral I am enabled to remove it from the vessel A and thoroughly clean it as occasion requires.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an oil-cleansing apparatus, a vessel, and an inner oil-receptacle adapted to be placed in the vessel, said oil-receptacle comprising an upper chamber, a separating-plate below the chamber, a partition secured to the separating-plate, and dividing the vessel into two vertical chambers, and means for conveyin g the oil from the separating-plate through the two chambers in succession.

2. In an oil-cleansing apparatus, a vessel, and an integral inner oil-receptacle adapted to be placed in the vessel, said oil-receptacle comprising an upper chamber, a separatingplate below the chamber, a partition secured to the separating-plate and dividing the vessel into two vertical chambers, and means for causing the oil to pass through first one chamber and then through the other.

In an oil-cleansing apparatus, a vessel, and an inner oil-receptacle adapted to be placed in the vessel, said oil-receptacle com prising an upper chamber having an inclined bottom, an inclined separating-plate secured below the chamber, a partition secured to the separating-plate and adapted to divide the vessel into two vertical chambers, a convoying-pipe secured to the separating-plate for conveying the oil through the first chamber, and a second pipe secured to the partition for conveying the oil through the second chamber, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID \V. GOULD.
